Identify the error in this column:
(x2 + 3x + 18) = (x + 3)(x + 6)
Answers
Answer:
I think the error is that the variable x came before the whole number 2.
[tex]x^2+3x+18 = (x+3)(x+6)[/tex]
↝ The error here is that (x+3)(x+6) doesn't make 3x in the middle here.
↝ From (x+a)(x+b) = x²+bx+ax+ab = x²+(a+b)x+ab
Now we let a = 3 and b = 6
Let's check the answer.
Given a = 3 and b = 6 (From the polynomials given.)
(x+a)(x+b) = x²+(a+b)x+ab
(x+3)(x+6)=x²+(3+6)x+(3*6)
(x+3)(x+6)=x²+9x+18
As you can see that the error here is that (x+3)(x+6) doesn't make 3x in the middle of polynomial. Therefore the error here is only 3x as proven.

what is the parallel slope intercept form pls help?
Answers
If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.
[tex]-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b[/tex]
Now that we have the y-intercept, we can create the equation.
[tex]y = 4x - 17[/tex]
We can prove this by graphing both lines, like so.

Write the equation of a line through (2,4) and (-6, 8) in any form.
Answers
Answer:
Step-by-step explanation:
y=mx+c.... first find m(gradient/slope)
m=Y2-Y1/X2-X1
m=8-4/-6-2
m=4/-8
m=-1/2
Then find c
Take any point and fix in x and y
4=-1/2(2) +c
4=-1 +c
c=4+1=5
Therefore y=-1/2x+5
y+1/2x-5=0

I Q and G P A. a = 0.04. b = negative 0.9. I Q and Standardized Scores. A = 20. b = negative 924.
Next, Kiara uses the steps below to predict a student’s standardized test score based on the student’s GPA of 4.0.
Step 1 Write the equation of the trend line for IQ and GPA.
y = 0.04 x minus 0.9
Step 2 Write the equation of the trend line for IQ and standardized test score.
y = 20 x minus 924
Step 3 Find the IQ that is expected from a GPA of 4.0.
y = 0.04 x minus 0.9. 4 = 0.04 x minus 0.9. 4.9 = 0.04 x. 122.5 = x.
The IQ is about 122.5.
Step 4 Find the corresponding standardized test score for an IQ of 122.5.
122.5 = 20 x minus 924. 122.5 = 20 x minus 924. y = 523.
The standardized test score is 523.

As an estimation we are told 5 miles is 8 km.
Convert 7.5 miles to km
Answers
Since it’s as an estimation it’d be 12km.
Your just adding 2.5 miles to 5 miles. 2.5 miles is half of 5 miles so that’d equally be half of 8 kilometers. Which is 4 kilometers.
Add the 5 mile equivalent of 8 kilometers to the 2.5 mile equivalent of 4 kilometers, and you get 12km as an estimate.

Given the equation

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
[tex]4-2x-14=3x+15[/tex]
simplifying the equation by subtracting 14 from the L.H.S
[tex]-10-2x=3x+15[/tex]
Subtracting 15 from both sides
[tex]-10-2x-15=3x+15-15[/tex]
[tex]-25-2x=3x[/tex]
combining the like terms
[tex]-25=3x+2x[/tex]
[tex]-25=5x[/tex]
dividing both sides of the equation by 5
[tex]\frac{-25}{5}\:=\:\frac{5x}{5}[/tex]

Does this situation represent additive
Inverses? Explain.
Answers
Answer:
Yes, it does
Step-by-step explanation:
When we add a number to its additive inverse, the resulting value is zero
The first case is running up 10 flights which we consider positive
then he runs down 10 flights of stairs; this we can consider as - 10
So adding this together, we have -10 + 10 to give zero
What this mean is that we have added a number to its additive inverse
